We just moved here from the States. My newly turned 4 year old (June birthday) attended one year of 1/2 day preschool this past year. He would have done the same come September but we moved to London for 2 years. Am I able to have him do 1/2 day "nursery" come September or defer his entry until January? I am unfamiliar with the system for young 4 year olds. My daughter (age 7) will be attending either Holy Cross or Sulivan. Thanks in advance!
